could just be a different browser.

Mozilla based browsers (Firebird, Mozilla, Netscape) have a form of debug
mode.
Just type "javascript :" into the url bar, it will list all errors a bit more
comfortably than MSIE does.

as long as your scripts are being viewed through a PHP capable server and
the are working, the are not the problem, but I don't *think* there is a way
to debug PHP (would be very interested if I was wrong on that one).

PHP is as easy to debug as javascript is. If there is an error, PHP will tell
you what line and what character (much as IE does with javascript). You just
have to use an editor that tells you the line numbers.

As for a Venkman type debugger for PHP, have never seen one and would be as
interested as you are.

When testing your site, you need to do it with as many browser
combinations as possible... There are several factors that can change
the way your page/script are managed (In order of significance):

1. The Browser (IE, Mozilla/Netscape, Opera, Safari, Konqurer, etc)
2. The Browser Version (3.0, 4.01, 5.5, 6.0, etc)
3. The Operating System (Windows XP/2000/ME/98/95, Mac 9/X, Linux,
FreeBSD, Solaris, Irix, etc)
4. The Screen size and resolution (More important for appearance of HTML)
5. The process speed of the machine it runs on. (This is really only the
case if you have timing issues (race conditions) in your script)

The best bet, is to install as many browsers as you can on your own
systems, and when it is all done, have everyone involved test it on
their systems.

When a problem happens, make sure to get all of the information about
the user's setup, so you can try to replicate it.

Re: Javascript debug ?

Many thanks to all for your help.

I did my test with IE, Opera and RealOne an don't have any problem. But
somebody told me he have many error with the same configuration as I use.
Strange isn't it!..

Nah... That is not strange, because the two of you do not have the same
configuration. Something _has_ to be different. He may have different
security/cache settings... javascript may be disabled... It could be a
different version of IE, a different service pack on XP, etc.

There is something significantly different between you and your user,
and it is likely that other users will have the same difference.

What is the website in question?

Couldn't agree with you more. I'm in the final stages of testing an
intranet site. All users are suppose to have a particular
browser/software configuration.

A user sent me a message stating that a particular area of the web
site wasn't working. After much analysis of their settings I finally
(out of shear desperation) told them to turn the machine off and log
back in. It fixed the problem. Why? I have no idea. Maybe IT had
changed the proxy settings or something.

Well on storeys like this...at the college I was at last year they run two
MS Terminal Servers, one mirrored of the other, one server could not view
hotmail because for some reason it was not responding to the <meta
refresh....> tag that hotmail uses during login (well at least with their
old setup, I don't know if they still do).

both servers had all the same programs and service packs as well as updates
installed, the only difference is *possibly* the order they were installed
in.

just another example of how there is *always* a difference

I don't know what Venkman means, but if it is like the ones in VC++ or MSVB,
then dreamweaver MX supplies a way of doing this for javascript, neat
feature!

Venkman is the javascript debugger included with a lot of Mozilla based
browsers.

click "Recherche">"Te xte">"a">"OK"

view the source and look at what your php is pumping out:

<TD><font size="1" face="Verdana, Arial, Helvetica, sans-serif"><a
href="group_lis t.php?maingroup =APPLE" TARGET="main">A PPLE</FONT></TD>

a tag opens but does not close, my version of ie seems to have a fit if
enough items are brought up on screen, this may be the reason, i can't see
any other reasons
